Freezing blueberries is one of the easiest ways to enjoy their flavor long after the season ends. But to avoid ending up with a frozen clump of fruit, you’ll need to do it properly. Here’s a practical, step-by-step guide to freezing blueberries the right way and using them later in your recipes.
Should you wash blueberries?
It depends. Washing before freezing makes berries ready to use later but increases the risk of clumping and freezer burn if they’re not fully dry. If you go this route, pat them dry thoroughly.
Not washing preserves the natural waxy “bloom” that protects the berries from moisture and bacteria, and reduces freezer burn. Just remember to wash them before using.
What you’ll need
- Colander and clean towels (if washing)
- Rimmed baking sheets
- Parchment paper
- Zip-top freezer bags (plastic or silicone)
- Permanent marker for labeling
How to freeze blueberries step-by-step
- Sort the Berries
Remove stems, soft or moldy fruit. Use soft (but not spoiled) berries immediately for sauces or compotes. - Wash and Dry (Optional)
If washing, rinse gently and dry thoroughly on towels. Moisture causes clumping. - Flash-Freeze in a Single Layer
Spread berries on a parchment-lined baking sheet in one layer. Freeze for 2–4 hours or overnight. - Store Properly
Transfer frozen berries to labeled freezer bags. Remove as much air as possible. You can portion them based on your usual recipes (e.g., 1 cup ≈ 240 ml) for muffins.
Pro tips for freezing blueberries
Don’t overcrowd the baking sheet — spacing helps them freeze individually.
Clean hands help prevent contamination, especially if washing beforehand.
Wait until fully frozen before bagging to avoid clumps.
How to use frozen blueberries
Frozen blueberries are ideal for most recipes — no need to thaw in many cases.
Smoothies & Drinks: Use straight from the freezer.
Muffins, Cakes, Pudding: Add frozen; extend baking time slightly.
Pies: If pre-cooking the filling, frozen berries are fine. Otherwise, thaw and drain before baking.
Looking ahead
Freezing blueberries at their peak lets you enjoy their sweetness year-round, reduces waste, and keeps your kitchen stocked with a healthy, ready-to-use ingredient.
